Didn't see any of them live, but, as a Sky subscriber, I was able to catch up with either the highlights or full race replays of most. What I did do 'though on a couple of free Sundays was to have the 5Live radio coverage on through a single earpiece while out for a bike ride.

Back in the Schumacher era, I watched every race live, even Canada and Brazil which over here come on at about 5am in NZ.

These days, not a chance. I'll watch most races which come on at midnight here, but I'm not waiting till 1am and I'm definitely not getting up before 8am. There's no point seeing the races live anymore because they don't have free timing & scoring on the website. Now you've got to pay for it and it's only an app so I don't imagine I'd even be able to track the full field on a stupid little cellphone sized screen.

Watched some races live before the start and after the end of the UK motorsport season.
During April-October I'm usually at a track so record the races and usually watch as live. If I've found out the result beforehand then highlights and FF will do.
Don't bother with FPs, sometimes will record qually highlights and my race watching starts 5 minutes before the start and finishes before the awful podium interviews.
Since we have Sky that is the coverage I watch.

I used to watch 75%+ races live or listen to live radio commentary but gave that up around the time I stopped going to GPs (2006).
We had Bernievision via Sky for the one season it was on and watching free practice was new and fresh. 15+ years later it's same old same every event. Even Martin's gridwalk has no interest now.

The household will watch far more rugby and other sport than F1, even other motorsport will have more airtime than GP coverage.

I watch all races on dvr. I also record and watch fp2 and qualifying. The move to ESPN is likely to hinder my viewing of f1 overall. I imagine fp2 and qualifying will be on espn3 only, meaning i will probably miss most if not all of those sessions. Man the loss of nbcsn is gonna hurt...

This F1 season has been a great cure for my insomnia, and I finish the year feeling younger, fresher, and fighting fit. I only managed to stay awake through two races, the rest either sent me to sleep or just the idea of watching them sent me to sleep. Show me just a few moments of the pre-first-practice-warm-up-show and my lights go out.

I recorded the C4 coverage of every qualifying and race and watched it when I could. A lot of the races being in the middle of Saturday/Sunday would have seriously interfered with family time. Another advantage of recording is the ability to fast forward through the preamble (and the adverts) so I can just watch the action. My favourite races were the ones shown really early in the morning so I could get up before everyone else had, enjoy them (still recorded for the reasons above) without spoiling the family weekend.
Race highlights that were shown late on Sunday night I'd avoid anything that would tell me the result, and get up early on Monday morning and watch before coming to work.

I honestly can't remember. I know I watched Abu Dhabi, Brazil and the British GP but I think I watched the rest on the DVR having recorded them. Quite a number I didn't watch at all, despite them being recorded.

I plead other motorsport commitments, in the main, but I've definitely lost the obsessive streak I used to have.

Let's see Russia I watched live from halfway, the rest that I watched in full live were Baku, Silverstone, Malaysia and Abu Dhabi. If the BTCC was on, F1 would be watched later.

I managed to listen to Spain, Canada and possibly Monza (can't remember TBH!) live on the radio. And the only race I watched in highlights without even knowing who won before I watched was Austria funnily enough

As a friend has Sky we tend to go round to his for all the socially acceptably timed ones, making it a social occasion - bacon butties, or Pizza depending on the time of day, and possibly the odd beer. Others I've mainly caught with the C4 coverage recorded, particularly if its clashed with one of our own race weekends. Watched a few of the FP coverage when C4 have shown it.

Richard Murtha: Back Racing with CSCC, and another first, I've finally done a rolling start!

Watched all the Channel 4 races. Occasionally watched live on Now TV, which was normally £6.99 for 24 hours to Sky Sports but I got some gift card for christmas last year which covered some of those.

I also looked into bootleg streams this year and found that some of them are full HD that can cast to a chromecast. I was very pleased to find that an Indian sports channel used the C4 feed, which meant that I could watch the race live with DC and Ben and not have to listen to Croft and Kravitz.
